Ive just ordered a k&n induction kit from the local motorworld for my 2005 1.4 16v, it cost £90. ive done alot of searching and looks like k&N is the best for a low budget. Doesnt really increase hp at all, but sounds great, my mate has got one on his fiesta and sound norml until he hits bout 2000 revs then its a deep sound and you can hear it sucking the air in through the filter, plus not cutting or modifying your old airbox just clips on and off so you can change it back easily. When i get it fitted ill upload a vid and sum pics..
